Abstract
In smart substation, process level equipment and optical fiber virtual terminal connection have been adopted, which leads to the obvious differences in the maintenance and isolation mode of protection equipment.Operation and maintenance personnel are still accustomed to the operation mode of traditional physical circuit, and are not familiar with new technology and equipment, which increases the risk of maloperation.This paper summarizes the status quo of maintenance safety measures for secondary equipment in smart substation.The means of maintenance and isolation of protection and related equipment in smart substation are analyzed.A method of switching the maintenance state of secondary equipment is proposed, which defines the maintenance state of protection and related equipment, such as operation state, signal state, offline state, maintenance state and isolation state, following the working habits of conventional substations.All maintenance operations are simplified as switching between maintenance states.The proposed method reduces the working pressure of operation and maintenance personnel on site, and makes some practical exploration on the modeling and on-line monitoring of secondary circuit in smart substation.关键词
